Reversing left and right objects in call to Diff changes the diff.PropertyType returned (but not Property)

[malclear]

I diff'ed two instance of Order where a new OrderDetail instance had been added to the array of one: changedOrder. If the originalOrder was on the left in the function call, then the resulting diff.PropertyType evaluated to "System.Collections.Generic.List'1[Models.OrderDetail]", as expected. --> However, ifchangedOrder was on the left, then the diff.Property type evaluated to "Models.OrderDetail".

Note that in both cases, the diff.Property value was "OrderDetails" (with an 's'), which is the collection variable's name.

If you tell me the intended functionality, I might be able to open a PR for you.
